"It won't be one suspect a week until we get down to one suspect," Heller said. "But, a few episodes in, a few suspects have been knocked off the list."

The premiere also ended with Teresa Lisbon (Robin Tunney) in a worrisome state, presumably dead at the hands of Red John. But things may not be as they seem.

"Things look very bad for Lisbon at the end of that first episode. What I can tell you is that there is a very cryptic clue in that last sequence of episode one that will eventually explain — when all is revealed — what happened to Lisbon and why," Heller said.

While Heller was coy about said clues, he said that Lisbon fans don't have anything to worry about, for the most part. "I’m loath to give away too much, but for those people who love Lisbon, as I do, they needn’t worry too much. They should worry but you know …," he hinted.
